I purchased an Ikan VK7i-SU 7" HDMI Field Monitor With the Nikon EN-N Battery Plate. It has HDMI in and HDMI out, 1280 X 800 resolution, and it runs off either an AC adapter or a Nikon EN-EL 15 battery. $450. My decision required a lot of research. I hope it works out.

The Ikan VK7i arrived and broke the second I attached the battery plate to the monitor. The actual picture was beautiful, but the hardware components are cheaply built. I sent it back and am expecting delivery of a 7" Marshall monitor. At over twice the price, I'm expecting a better piece of kit. To be continued...

The Marshall is great, better than I expected. Too bad it's impossible to shoot action stills in real-time with live view on the d800. It's very handy for copy stand work and great for reviewing photos with clients. I also like it for setting up still life pictures.

here's a production shot from yesterday. To clearly show what is going on I cheated and had the camera I took the photo with trigger the lights instead of the one in the picture. The white background is the fill light: a 6 x 6 foot Chimera frame with a 1/2 stop scrim and behind that is an Einstein 640 monolight firing into an umbrella. The spotlight on the flies is a Lumopro LP 180 in a mount I made to use battery powered flash with a Plume,ltd. Chimney grid holder/reflector. A speedotron 3 degree grid is mounted in the Chimney.

I'm late to the party as usual but have you looked at the offerings from Small HD? I have the DP6 and use it primarily for video but have used it for stills off a D600 flown on a 15 foot boom (trigger is FW) 2 stories up. Worked great.
